Confused? Windtunnel Supreme VS Lindhaus Activa 30

Indeed Nar ....it sounds like your Vax has the patented Hoover WindTunnel brush chamber. It's basically a thin suction channel that goes over the brush roll to bring strong suction to a ledge on the front edge of the cleaner. This picks up dirt that has been flung forward by the spinning brush roll. It actually works quite well. You just have to clean the channel every so often as it can easily get clogged because it's so thin.

I think the design of the very first WT brush roll enclosure also creates a third pathway behind the brush roll, if I remember correctly. I can't remember but again, it basically adds another intensified suction path in the chamber. I'm sure if you search for WindTunnel maintenance on YouTube, you'll see what the channels look like when needing cleaning.

Yes, Hoover's new descriptions are weird! Some are marked 2 channel and some are marked 3 channel. I think the ones marked 3 channel are the original Windtunnel design and the ones marked 2 channel are more of a gimmick and just using the name Windtunnel!!!

The original Windtunnel design had the same inlet as a normal upright with air flow leading to the housing. BUT, it added ducts along the front and rear of the entire agitator cavity to capture dirt into those air directs off of the brush roll to further prevent the brush roll from carrying dirt back down into the rug. In taking apart the nozzle, it is very easy to remove a the large duct and give a cleaning on occasion.

In the homes of the ultra filthy and consumers who let their machines clog up, these Windtunnel ducts can collect a mass of dirt over time. But in households that are maintained as should be with vacuuming at least every 2 weeks and bags not overstuffed, the channels will collect dust but should not fill up!

Ah I just looked at the brush roll floor head cover - and I forgot it says Windtunnel on the side corner lol. However I do find the Cordless Air picks up a lot more dirt from the floor head than from the hose. The clear floor head gets dirty all of the time which is a shame but more so the Windtunnel insert strip that often needs to be unscrewed, taken off and wiped before installing again. One of the downsides I suppose to having a modern bagless cordless vac that uses clear floor head covers.

Yes...any clear plastic used for vacuum parts that will touch dirt get cloudy really fast: bagless dust bins, clear hoses, clear mini turbo tools, clear brush roll chambers. I always gave the brush roll cavity in our our top-rated Hoover WindTunnel Ultra Self-Propelled a good wet wipedown whenever changing the bag and checking the brushroll. The WindTunnel segregated suction channel was accessible after removing one or two screws if I remember correctly.
